      If you want to output some binary data such as image from PHP
      script with PHP 4.3.0 or later, Content-Type: header must be send
      using <A
HREF="function.header.html"
><B
CLASS="function"
>header()</B
></A
> before any binary data was send
      to client (e.g. header("Content-Type: image/png")).
      If Content-Type: header was send, output character encoding
      conversion will not be performed.
     </P

      <A
HREF="function.header.html"
><B
CLASS="function"

      encoding conversion will be performed using character encoding
      settings.
